Summited around 2 pm after spending the night on the Sahale - Boston Col. We knocked off Sahale in the morning and then descended down to Sharkfin Tower along the Quien Sabe Glacier. We climbed moderate fifth class rock around the moat at the base of the snow gully and then gained access to the snow half a pitch above. The quality of the rock on the Southeast Ridge was great, as were the views of Buckner, Sahale, Forbidden, and Eldorado.
